How Listeria monocytogenes can survive in extreme environmental conditions


It is difficult to eliminate L. monocytogenes from post processing contamination of food production lines since this pathogen is common in various environments outside processing plants, and can endure in food processing environments. Listeria monocytogenes has better survival ability than most other food pathogens, resulting in the colonization of Listeria in food processing environment. In the recent past, researchers have identified several hypervariable (easily changeable regions) regions of the bacterial genome called Genetic Insert Stress Survival Islet 1 (SSI-1). The SSI-1 is a five-gene islet that contributes to the growth of L. monocytogenes in suboptimal conditions ..… Read More at BioExpert Corner.
